Application filed August 7, 1924. Serial No.. 730,699.`

This invention relates to map heads or binders for supporting maps andprovides means whereby the maps may be either hung up or mounted on astand or rolled around the head as for shipping or storage purposes. Thepresent invention provides means whereby a number of maps may besupported on one head or cross piece and the tops or edges where themaps are supported may be firmly pressed or bound together in order tosupport the maps without tearing. My improved head or binding devicealso provides means for protecting or stilfening the maps when they arerolled upon the same and means whereby the maps may be readily adjustedfor exposing different maps in the series. Other objects of thisinvention are to provide a map head made of few parts but which will bereadily adjustable for different numbers of maps or other sheets; toprovide a simple and efficient binding and supporting member for maps,sheets or the like; and, in general, to provide such an improved` deviceas will be more fully described hereinafter.

In the acompanying drawings illustrating this invention;

Figure 1 is a front View showing the device in hanging position;

Figure 2 is an enlarged sectional view taken on the line 2-2 of Figure1;

Figure 3 is an enlarged sectional view taken on the line 3-3 of Figure 1and showing the head in reversed position for supporting maps on thestand; and

Figure et is an enlarged front view showing the hanger in closedposition.

In the particular form of my invention as shown in these drawings thehead comprises two main strips or supporting members 5 and 6 which arepreferably made of sheet metal such as steel or the like. The strip orbar 5 is provided with curved flanges or rolled edges 7 and 8. Theseflanges are disposed on opposite sides of the strip w so that the stripis S-shaped in cross section. The plate or strip 6 is provided with arolled edge or flange 9 at one edge thereof and is oppositely disposedto the flange 8. The binding edges of the articles to be supported suchas sheets or maps 10 are positioned between the strips 5 and 6 as shownparticularly in Figure 2 and bolts 11 extend through the strips andsheets to hold the parts together. When the nuts 12 are tightened theedges of the maps Will be held together and in position by friction sothat they are not apt to become torn and they are further protected bythe rolled edge 7 which makes a back for the binding pieces. `Suchflanged strips or plates are very ,Stiff in proportion to their weightand provide a substantial roller or stiffening member around which themaps may `be rolled and the curved edges prevent the maps from beingcreased or bent when rolled around the head. The head is provided withclips or hangers 13 for supporting the maps when they are to be hung onthe wall. These clips have holes for receiving the bolts 11 and are heldby nuts 14. Their opposite ends are provided with holes 15 forengagement with screws, nails or the like on the wall. Then the maps areto be rolled on the head, these clips may be swung to folded position asshown in Figure 4.

The plate or strip 5 is provided with a socket 16 for receiving the rodor supporting stem as indicated in dotted lines 17. When the head issupported in this position, the rolled edges 8 and 9 are at the top andthe maps or leaves may be fol-ded from one side to the other asillustrated in Figure 3 and will be supported over these rolled edges sothat they are not apt to be creased or broken. My improved head providesmeans whereby it may be adjusted for different numbers of maps or leavesand when so adjusted it will hold such maps or leaves securely together.The head or supporting device may be made in various sizes and Vmay bemodified for different conditions and therefore I do not wish to belimited to the exact E arrangement herein shown and described, eXcept aspointed out in the following claims, in which I claim:

1. A map head comprising a rigid strip having oppositely disposed rollededges, a second rigid strip having one rolled edge and means forfastening the strips together to hold the sheets therebetween.

2. A map head comprising a metallic strip of substantially S-shape incross section, a. second strip of substantially the sam-e width as thefirst strip and having a rolled edge along one side thereof and boltsfor fastening the strips together and clamping maps or the like betweenthe same.

3. A map head comprising two stiff strips having longitudinal flanges,bolts for fastening the strips together and hangers engaging with saidbolts. v

4. A map head comprising two strips having longitudinal flanges, asocket on one of said strips for receiving a supporting rod and meansfor fastening the strips together.

5. The combination with one or more maps or sheets, of a pair ofmetallic binding strips having oppositely disposed curved flanges forstiening the same, and over which the maps may be Jfolded, boltseXtending through said strips and maps, and clips engaging With saidbolts. Y

6. The combination With a plurality of maps, of a binding strip havingoppositely disposed rolled edges, onek of said rolled edges projectingover the binding edges of the maps, a second strip having a rolled edgearranged oppositely to the lower rolled edge of the first named strip,bolts passing through said strips at the edges ofthe maps and means forsupporting said head.

7. A map head comprising a sheet metal plate having upper and lowercurved anges, a second strip having a Curved flange disposed oppositelyto the lower curved flange oi the i'irst named strip and bolts or thelike passing through said strips for pressing tliem against the maps,the arrangement being sueh that the maps may be rolled around saidcurved flanges Without being readily creased or broken, substantially asdescribed.
